Blooger api and metadata

UPDATE: Sorry, I understood I made some mistakes. I'm using flat api now anyway, so these questions are not actual anymore.

I'm using xmlrpc api to post. This is description:http://www.livejournal.com/doc/server/ljp.csp.xml-rpc.postevent.html

It works, but I can't figure how to get posting metadata working.Description from the page above is not very clear:

props(optional): Set arbitrary (but restricted) meta-data properties to this log item. See Chapter 12: Journal Item Meta-data for the documentation of the keys and value data types.

Now questions:1)Is posting metadata using xmlrpc api is working at all?2)Can someone please supply an example of xmlrpc metadata posting (only that part)? I tried to use simple struct and struct inside array, but these are not working (I tried "current_mood" and "current_music"3)Does metadata support include lj tags?
